For many companies, keeping their operations running smoothly with a supply of fuel in a remote location can create a number of expensive challenges. Few remote sites have year-round access for ground tanker trucks or water access for barges, which means most are forced to use fixed-wing aircraft or helicopters to transport drums of fuel.

Because fuel cannot be carried at the same time as passengers, whole aircraft must be set aside to do this job. In addition, fuel drums are not shaped to fit inside an aircraft, which means the craft never achieves its full carrying capacity.
